TBM cutterhead and TBM

Abstract

The invention discloses a TBM cutterhead and a TBM. The TBM cutterhead comprises a cutterhead body, and the cutterhead body comprises a panel and a back plate which is in butt joint with the rear side, in the axial direction, of the panel; the panel is provided with a center zone, a conical surface zone surrounding the periphery of the center zone, and an annular surface zone surrounding the periphery of the conical surface zone from the center of the panel to the edge in sequence; the conical surface zone gradually inclines towards the back in the axial direction through the connection line between the conical surface zone and the center zone; the annular surface zone is an annular surface; the cutterhead body is internally provided with a slag sliding plate and a slag receiving hopper; one end of the slag sliding plate is in butt joint with the conical surface zone, and the other end extends towards an inlet of the slag receiving hopper; a field angle is formed between the slag sliding plate and the conical surface zone, and an opening faces towards a center shaft of the cutterhead body; and the position, located on the outer side of the connection line of the slag sliding plateand the panel, of the panel is provided with a slag inlet, and the slag inlet is provided with a bucket. When the TBM cutterhead is applied to inclined shaft tunneling through a forward tunneling method, slag can fall into the slag receiving hopper through self weight, slag discharging is facilitated, the slag sliding plate is connected to the conical surface zone, and thus, the time for the slagto sliding on the slag sliding plate can be shortened.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a TBM cutter head and a TBM. Background technique [0002] In the existing inclined shaft excavation, a typical method is to adopt the front shaft method for construction, which is safe in construction, and can also save costs and shorten the construction period. However, using the current common cutter head to excavate inclined shaft tunnels cannot meet the requirements for inclined tunnels in the fields of coal mines and water conservancy projects due to the difficulty of slag removal. [0003] Therefore, how to facilitate the slag removal of the cutter head is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0004] In view of this, the object of the present invention is to provide a TBM cutter head, which is convenient for slag removal when it is applied to the digging and exiting of inclined shafts by the ...
